Even though powder coating finishes can last up to 20 years, exposure to UV light and other outdoor elements may break it down faster. This process is called chalking, and it causes the resin and pigment particles in powder coating to lose adhesion.

Does powder coating fade in sun?
Sun exposure or direct sunlight breaks down the particles within the paint which then makes the coating fade.
Is powder coating UV resistant?
From protection against things like corrosion and rust, to the uniformed and impressive aesthetics once your equipment has been coated — powder coating has a lot to offer. However, there’s one benefit to powder coating that many often overlook, and that’s UV-resistance.
Is powder coating OK for outside?
The powder coating finishes are not only sturdy but flexible as well. It can be used on different surfaces, including metal, concrete, steel, and plastic. It’s suitable for both indoor and outdoor applications, and it’s one of the most cost-effective finish options.
Does powder coating hold up to heat?
The most common powder coatings can withstand temperatures between ambient to 200°F, although most are on the lower end of the spectrum. These general powders will do the trick for most typical applications, but may be susceptible to significant color change and other issues once you start pushing that 200°F+ range.
What are the disadvantages of powder coating?
Although powder coating has many advantages, it also has disadvantages as well, including the following.
- WILL BREAK DOWN IF EXPOSED TO UV RAYS.
- COLOR CHANGE DIFFICULTIES.
- START UP COSTS ARE GENERALLY HIGH.
- DIFFICULT TO TOUCH UP WHEN MARRED.
- PART HAS TO BE GROUNDED IN ORDER TO POWDER COAT.
How long does powder coating last outside?
In the United States, that often means South Florida and sometimes Arizona. Entry-level outdoor-durable powder coatings keep their color and gloss for 12-18 months after the application. After that, they fade and are up to 50% less glossy.
What is the most durable powder coating?
Epoxies. Epoxies were the first widely used powders. They are very durable, offer excellent hardness and have arguably the best chemical and corrosion resistance of all available powders.
Is powder coating oil resistant?
Powder coating is more resistant to chips, abrasions, UV light, petroleum products (gas, oil) and chemicals than solvent based “wet” coatings.
How do you keep powder coating from rusting?
If you want to get the best possible corrosion on a blasted surface, use a zinc-rich powder primer. The zinc in the prime layer provides barrier protection against moisture penetration to the steel surface. If you cannot blast or choose not to blast, you can increase the performance by improving the pretreatment.
Is powder coating better than paint?
Powder coating provides better performance than wet paint—it is more resistant to chipping, scratching, and other wear because of the thermal bonding it undergoes during curing, and because it can be applied in much thicker layers.
Is powder coating as good as Galvanising?
For any application, powder coating offers distinct advantages over galvanizing. While galvanizing has a reputation for durability against the elements, today’s powder coatings provide a worthy match. Options like Super Durable Powders offer even more protection from the sun and ultraviolet light.
Does powder coated aluminum get hot in the sun?
Unlike iron, aluminum naturally disperses the heat, greatly reducing its temperature. Now, if it’s 90 degrees Fahrenheit outside, you should still check the cast aluminum before touching it just to be safe, but trust us, it will be about 100% cooler than any other metal in your backyard.
Can you powder coat over powder coat?
The Short Answer. Put simply, the answer – most of the time – is yes. There’s nothing about powder coating that makes the material fundamentally incompatible with more powder coating. You can still have the powder applied and cured to form a new coating that looks just like new, in most cases.
Can I paint over powder coat?
Normally, powder coating has a slick surface which does not allow paint to stick. Sanding it down carefully will enable you to paint on it effectively. Wipe down the area you will be painting with an appropriate solvent cleaner. Finally, rinse it down with warm water, then allow it to dry.
Is powder coating worth the money?
In many instances, powder coating is the superior finishing option for its durability, texture and ease of application. It can stay on for years and protect your parts from corrosion and rust. Powder coats look good in any home and offer a much safer application process than spray paint.
Does powder coating last longer than paint?
Since powder finishes are stronger and more durable than paint coats, powder will generally guarantee superior, longer-lasting protection to the surfaces of metal-bodied products.
How long does powder coating take to harden?
Powder coating is not like traditional, liquid paint, it does not dry it has to be heated in an oven to cure this process takes 10-15 minutes dependent on the powder type and to achieve the correct properties it must follow the correct curing process.
Is powder coated waterproof?
Polyester powder coating (PPC) is an increasingly popular alternative to wet paint finishes, and one of its basic qualities is that it is waterproof. However, this is far from the only advantage powder coating enjoys over traditional paint materials.
How do you restore faded powder coating?
Repair faded powder coating
By rubbing with cutting compound the surface will be removed and new paint exposed with its original colour. However, if the original coating was a matt finish it will now have been polished to a gloss.
How strong is powder coating?
Powder coating protects the roughest, toughest machinery as well as the household items you depend on daily. It provides a more durable finish than liquid paints can offer, while still providing an attractive finish.
